In April, a world-wide outbreak of H1N1, also known as the "swine flu" stirred fears of an impending "pandemic." U.S. officials declared a national health emergency and rushed to produce millions of vaccines before the height of the Fall flu season.

While most experts agreed that the H1N1 virus deserved this reaction, other interpretations cast doubt on the severity and on the effectiveness of the vaccine.

By October, the Centers for Disease Control warned that the H1N1 virus was active states across the country. Thousands of documented fatalities motivated parents and school officials to vaccinate their children and students, even as government health officials scrambled to keep production of the vaccine up with the increased demand.
